Analog semiconductors are electronic components that process continuous signals, which can vary in amplitude and frequency. Unlike digital semiconductors, which work with discrete values (0s and 1s), analog devices handle real-world signals such as sound, light, and temperature. Common examples include operational amplifiers, transistors, and diodes. These components are essential in various applications, including audio equipment, radio frequency devices, and sensor systems. They enable the conversion of physical phenomena into electrical signals, allowing for the manipulation and amplification of these signals in devices like smartphones and medical instruments.
